Description

Methyl Bromide CAS NO 74-83-9 is a highly effective and fast-acting fumigant gas. It matters for its broad-spectrum pesticidal activity against insects, nematodes, rodents, and fungi, making it a critical tool for commodity and soil treatment. Industries requiring stringent pre-shipment quarantine, soil sterilization, or structural fumigation, such as agriculture, international shipping, and food storage, rely on its efficacy.

Application

• Commodity and Structural Fumigation: Used for disinfecting stored grains, dried fruits, nuts, timber, and other durable commodities, as well as warehouses, mills, and shipping containers to eliminate pests.
• Soil Sterilization (Pre-Planting): Applied to agricultural soils to control soil-borne pathogens, nematodes, weed seeds, and insects before planting high-value crops.
• Quarantine and Pre-Shipment (QPS) Treatments: Critical for meeting international phytosanitary regulations to prevent the cross-border spread of pests on wood packaging materials and other regulated articles.
• Greenhouse and Nursery Sanitation: Used to fumigate greenhouse soils and potting media to ensure a pest-free start for seedlings and ornamental plants.
• Historical Use in Fire Extinguishers: Previously utilized as an effective fire suppression agent in specialized portable fire extinguishers.
• Chemical Synthesis Intermediate: Serves as a methylating agent in organic synthesis for the production of pharmaceuticals and other fine chemicals.

Quality Control

Our Methyl Bromide is produced and handled under strict quality protocols to ensure consistency and purity for industrial applications. While its use is heavily regulated under the Montreal Protocol, we ensure our product meets the stringent specifications required for approved Critical Use Exemptions (CUEs) and Quarantine and Pre-Shipment (QPS) applications. A Certificate of Analysis (COA) detailing purity and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed, approved pressure-rated container, protected from light and heat sources. Store in a cool, well-ventilated, dedicated area away from incompatible materials. Due to its highly volatile and gaseous nature under ambient conditions, containers must be kept upright and secured. Storage temperature should not exceed 40°C (104°F).
